修改bootstrap-datepicker.js
1. 檔案開頭加入pad函數
(function ($, undefined) {
var pad = function (val, len) {
val = String(val);
len = len || 2;
while (val.length < len) val = "0" + val;
return val;
};
2. fill字段增加西元年及民國年轉換
fill: function () {
var d = new Date(this.viewDate),
year = d.getUTCFullYear(),
month = d.getUTCMonth(),
startYear = this.o.startDate !== -Infinity ? this.o.startDate.getUTCFullYear() : -Infinity,

cleartxt = dates[this.o.language].clear || dates['en'].clear || '',
tooltip;

// Calendar week: ms between thursdays, div ms per day, div 7 days
calWeek = (th - yth) / 864e5 / 7 + 1;
html.push('
' + calWeek + '
');
}
}
clsName = this.getClassNames(prevMonth);
clsName.push('day');
if (this.o.beforeShowDay !== $.noop) {
var before = this.o.beforeShowDay(this._utc_to_local(prevMonth));
if (before === undefined)

}
this.picker.find('.datepicker-days tbody').empty().append(html.join(''));
var months = this.picker.find('.datepicker-months')
.find('th:eq(1)')
.text(year - (this.o.language == "zh-TW" ? 1911 : 0))
.end()

3. click字段加入西元年及民國年轉換
click: function (e) {
e.preventDefault();
var target = $(e.target).closest('span, td, th'),
year, month, day;
if (target.length === 1) {
switch (target[0].nodeName.toLowerCase()) {

this.showMode(1);
break;

case 'next':
var dir = DPGlobal.modes[this.viewMode].navStep * (target[0].className === 'prev' ? -1 : 1);
switch (this.viewMode) {
case 0:
this.viewDate = this.moveMonth(this.viewDate, dir);
this._trigger('changeMonth', this.viewDate);
break;
case 1:
case 2:
this.viewDate = this.moveYear(this.viewDate, dir);
if (this.viewMode === 1)
this._trigger('changeYear', this.viewDate);
break;
}
this.fill();
break;
case 'today':
var date = new Date();
date = UTCDate(date.getFullYear(), date.getMonth(), date.getDate(), 0, 0, 0);
this.showMode(-2);
var which = this.o.todayBtn === 'linked' ? null : 'view';
this._setDate(date, which);
break;
case 'clear':

}
break;
}
}
if (this.picker.is(':visible') && this._focused_from) {
$(this._focused_from).focus();
}
delete this._focused_from;
},
4. validParts中年份檢查pattern修正
validParts: /dd?|DD?|mm?|MM?|y{2,4}/g,
5. parseDate中加入西元年及民國年轉換
parseDate: function (date, format, language) {
if (!date)
return undefined;

6. formatDate字段加入西元年及民國年轉換
formatDate: function (date, format, language) {
if (!date)
return '';
if (typeof format === 'string')
format = DPGlobal.parseFormat(format);
var val = {
d: date.getUTCDate(),
D: dates[language].daysShort[date.getUTCDay()],

m: date.getUTCMonth() + 1,
M: dates[language].monthsShort[date.getUTCMonth()],
MM: dates[language].months[date.getUTCMonth()],
yy: date.getUTCFullYear().toString().substring(2),
yyy: pad(date.getUTCFullYear() - 1911, 3),
yyyy: date.getUTCFullYear()
};
val.dd = (val.d < 10 ? '0' : '') + val.d;
val.mm = (val.m < 10 ? '0' : '') + val.m;
date = [];
var seps = $.extend([], format.separators);
